UNITE? DUPI-IQATINQ APPARA US- forming part of Letters Patent ll'o. 530,771, dated December 11,1894. I Applicatien filed June 1894s ltlflhdt No sea ed v I Y I 5' Mn .To all whom it may concern:

Be it known that I, IRVING S. HAYNES, a citizen of the United States, and a resident of New York, in the county of New Yams-e State of New York,havei-n'vented-certain new and useful Improvements in Duplicating ieip paratus, of which the following is e speeifica- 5 ion. '1 My invention has reference to duplicating f apparatus, and its object is to construct an apparatus for use in printing from stencil plates or sheets, whereby the inconvenience of inking the s'teneilandrenioving' tlieprinted sheet, and also the liability to biurorsaear' the paper while being printed, will be reduced to a minimum'or entirely done away with. I A further object of the invention is to so i construct the apparatus that whnnot; in use it may be stowed away in 'tlie'stand upon which it is mounted, and the latter t-hen be i used as a deskor tablei Y 71 I it? The invention will be described with reference to the which- 7 Figure 1 is a sectional view of my imy proved apparatus; "Fig. 2 is aside elevationfl with parts broken away, showing the 'p'esition of the parts when the roller is at the forward end of the stencilshe'e't and Figi3 is a" plan View of the apparatus-in the p'ositio' shown in Fig. 1; i 2 Referrin'g' to the drawings by letter, A rep resents a stand or receptacle suitable-for the support of the apparatus.-

Any stander table maybe usedgbut-l preferto use' a bok, as5- shown, for reasonswhich will hereinatterf more fully appear. 'rneie s a, a, dy-d'g' are 1 suitably notched or otherwise adapted to fQ-f ceive and support the platen-b; to -whieh-is hinged thevibratin gsten'ci'l-frame c earrying the stenci'l'sh'eet 'c." Amherear oft-heframel and inclined slightly upward'therefromis'an inkingplate' d, or other equivalent device for" supplying ink to the rollere', which isadapted to moveback and forth in the iiianner tolie hereinafter described. At eac'h" side of the platen is pivoted a supporting rod fadapted' to be raised and lowered bymeans of swin ing links f f, at each 'end," sothat when the links are substantially vertical, the top of the accompanyiilg raw ngs; in

od will be high enough to prevent the roller from touching the stencil sheet when moving as 'will be described hereinafter; 11 The oppos site ends of the links f'g f fl -are pivoted to the legs a'ja' rendering the rod capable of a rock.- ing=motion,'it dropping 'down below the stencilfframewhen the upper ends 'ofth'e: links f", fi are swung forward The rod f is :prowided-w-ith a lug or raised portion 7 f At each 'Side of the platen i sipivote'd'an armlg and an arm'h, 'each capable of l swinging or rocking motion and connected to the other by a connecting arm 2'. The arms on each sidefof 3 th'e' apparatus are respectivelyiconneete'd to the cor-responding 'one'sonthe. other 'sideiby cross braces g, 'h',-so that the whole will: form a=frame capable of s-winging' fori 'ward and backwards- Aflexible strapm has one of: its en'ds'fastened to rod f andthe other fastened to theswinging frame andis so adjustedthat wheir'the frame is in its vertical .posi'ti'on'the strapwill be taut and rod f draw-n to its highest position. -i A flexible strap 'n is fastened atone end to the stencil frame :0 and swinging frame=is rocked forward and back- ?wardr fI Oit-heupper end-of arms=h,"or' an.y "other part of the" swinging frame, ispivoted l 'at'the other end tothe swinging' frame, and 1 adjustedto lo'werand r-ai'sethe stencil as-the a-roller carrier consisting-of two side rodslk,

It; connected by braces 70, k The'roller eis fixed-thereto by any convenient means and tspressureupon the ink plate. and stencil is rgulated byrmea'ns' of weightski upon the roller carrier.- *The ends of the arms is proje'ct a shortdistance beyond the roller and %below the sidesof' the ink plate, :as indicated in the drawings. x

- The operation 'of the apparatus is as follows: When-theswingi-nglframe is in its ver-' tic'al position, as shown in Fig. 1, the roller 'e 'Wilhbe-uponthe rear of the inking plate (1; fthe- 'strapn w-ill be drawnib'a'ck and stencil ;fram'e=c" raised; and straps m drawn tauti so thatrods f are raised to "their highest position. ilhe paper to be printed uponis. then laid upon platen b and the swinging frame g; h, t'iswun'g forward, i causing the .rollerto advance toward the stencil and the stencil frame to drop in position upon the platen by reason of'the slackening of strap '11. When th'erollerreach es the forward end of the plate, the projectingends of the carrier, 70, k, will ICO come in contact with rods faud slide forward thereupon, thus keeping the ink roller raised above and out of contact with the stencil sheet. Upon reaching the end of the stencil the ends 7c, 7r, strike againstlugs f and push them forward, the straps at having in the meantimebecomeslack. Thispushestherods f down to their lowest position and drops the roller on to the stencil frame, in the position shown in Fig. 2 of the drawings. The rocking or swinging frame g, h, t, is then swung backward, drawing after it the roller e, which, being weighted by the weights k bears heavily upon the stencil sheet and forces ink through the same and upon the paper to be printed. When the roller has been drawn back upon the ink plate, the stencil frame will be lifted, and the rodsfraised to their highest level, by the tightening of straps n and m. The apparatus is then ready for the removal of the printed sheet and the insertion of another sheet to be printed in the same manner.

In the construction of my apparatus it is immaterial whether or not the various parts be of the relative proportions indicated in the drawings. They may be varied or altered; and it is pointed out that the arms g, and arms 11 which connect arms g to arms h, may be dispensed with without greatly detracting from the utility of the apparatus. In that case the straps m would be connected to arms 71 instead of arms g as shown. Furthermore, it is to be understood that although I have described the machine as having one arm of each pair of the arms of the frame pivoted on each side of the machine, the frame may be made up of arms, singly or in pairs, pivoted to either side of the apparatus; and, although I have described the apparatus as having a supporting rod f on each side, it is obvious that only one rod would accomplish the same result as two or more. The length of the links f,f and consequent height of rods f, as compared with the height of the platen b 0, may also be regulated at pleasure by making the projecting ends of the rollercarrier, 7c, 71:, longer or shorter as desired. The type of platen and stencil frame used is unimportant. The apparatus may be adapted to receive and print from any of the common types of mimeograph, neostyle, cyclostyle, &O.

In the drawings I have illustrated the apparatus installed in an inclosing box A and prefer to so install it, in order that the apparatus, when not in use, may be folded up inside of the box and the box then used as a desk or table by providing a suitable cover therefor. With this end in view the platen b and stencil frame 0, and inking plate (1 with its support (1', are adapted to be removed from their supporting legs a, a and the side of the box A, and the legs a, a are hinged to the box in such manner that they may be folded one above the other on the bottom of the box, or otherwise arranged to withdraw their support from the platen b. The swingnation of a platen, a stencil adapted to rest.
